It was March 4, 1918, and the massive USS Cyclops was on a routine voyage from Brazil to Baltimore, with over 300 crew members on board. But the Cyclops would never arrive in Baltimore, and no trace of its crew would ever be found. A prevailing theory is that the Cyclops was lost in a storm. The ship was known to be top-heavy and prone to listing, but due to the fact that it disappeared during World War I, some favor the belief that the Cyclops was sunk by a German U-boat. One of the most plausible theories is that the Cyclops was simply overloaded. Although it had been approved for its journey to Baltimore, reports show that the ship's water level was over the Plimsoll line, indicating overweight cargo. While this could have caused the ship to become unbalanced and ultimately sink, it doesn't explain why no wreckage or debris was ever found. While we may never fully know the fate of the USS Cyclops, it's interesting to note that it had three sister ships - the Jupiter, the Proteus, and the Nereus - all of which were also lost without a trace.

Born in 1897 in Atchison, Kansas, Amelia Earhart was a groundbreaking pilot and feminist icon. She set numerous altitude and speed records throughout her career in the aviation world, and was the first woman to fly solo across the Atlantic Ocean. In June 1937, Earhart and her navigator, Fred Noonan, set out on a 29,000-mile journey to travel across the globe - a voyage they would never finish. In July, while attempting to locate the remote Howland Island in the Pacific Ocean, contact with Earhart's plane was suddenly lost. Despite extensive search efforts, no trace of Earhart and Noonan was ever found. One theory is that they crash-landed into the pacific and drowned; another is that they made an emergency landing on the nearby uninhabited island of Nikumaroro, eventually succumbing to the elements. The discovery of various artifacts on the island, such as clothing remnants, has lent credence to this theory, but nothing conclusive has been found.
